A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights ① that follow a resident's schedule no longer need to be switched on and off by hand. These small conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns ② which settings match each household's actual habits rather than a factory default. Over months of use, the system becomes noticeably better at ③ anticipate needs, often adjusting settings moments before a resident would have reached for a switch. Yet convenience comes with a trade-off that many households ④ overlook. Every one of these small adjustments depends on constant data collection, meaning that a detailed record of when people wake, leave, and return home is quietly ⑤ being stored somewhere beyond their immediate control.

Telemedicine, which allows patients to consult doctors through video calls rather than in-person visits, ①have expanded rapidly since its early adoption. Supporters argue that this approach saves patients considerable time and ②makes healthcare accessible to people living in remote areas without nearby hospitals. It has also created new career opportunities, ③since healthcare providers now need staff skilled in digital communication. However, critics contend that virtual appointments cannot fully replace physical examinations, ④which remain essential for detecting certain conditions. Despite such concerns, most healthcare experts believe telemedicine will continue to grow, ⑤complementing rather than replacing traditional in-person care.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. During recent years, this gap became impossible to ignore, as families in rural areas or low-income neighborhoods ① struggled to complete schoolwork that assumed a stable connection and a personal device. Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure ② essential to modern life. That assumption is increasingly ③ reconsidering, particularly as more essential services, from job applications to medical appointments, move online by default. Closing this divide will require more than simply distributing devices; it will demand sustained investment in the physical networks ④ that carry information into every home, ⑤ regardless of income or location.

Imagine a man locked inside a room who does not understand a single word of Chinese, yet who ① possesses a giant rulebook written entirely in English. Slips of paper covered with Chinese characters ② are passed in through a slot, and by following the rulebook's instructions step by step, he produces replies that appear fluent to anyone outside. From the perspective of a native speaker reading the responses, the room seems ③ understanding Chinese perfectly. Yet the man inside understands nothing at all; he is merely manipulating shapes according to formal rules, without ④ grasping their meaning. This scenario was designed to challenge the assumption that a computer running a sophisticated program truly understands language simply because it produces convincing output, ⑤ passing every external test of intelligence.

Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, ① tamper-resistant ledger rather than through a bank or government agency. In theory, this design distributes power away from any single institution and toward the network as a whole. In practice, however, a small number of large players have come to ② dominate many blockchain networks, controlling enough computing power or currency to influence outcomes that were supposed to be decided collectively. Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often ③ ample institutional support to appeal to, since the entire system was designed precisely to eliminate that kind of central authority. Whether decentralization can ④ survive this concentration of power remains one of the technology's most ⑤ unresolved questions.

The Hillside Community Center is looking for student volunteers to help with its summer programs. ___________. This opportunity is open to all middle and high school students who can commit at least four hours per week during July and August, and no prior experience is necessary since training will be provided.

City governments increasingly market dense networks of surveillance cameras as a safety upgrade. Yet the same infrastructure that catches criminals also creates a permanent record of where ordinary citizens go about their daily lives. Once a camera network exists, its purpose can quietly expand, often without new public debate. Civil liberties groups argue that _______________.

Every spring, the art club at Sejong High School creates one large mural together instead of individual paintings. The process begins with a session where members suggest themes and vote on their favorite idea. (A) Therefore, members regularly step back to compare their section with the rest of the mural. After several weekends, the teams combine their sections into a single image, and the finished mural is displayed near the entrance. (B) Once a theme is chosen, the club divides into small teams, each responsible for one section of the wall. One team sketches the outline while another mixes colors to match the design. (C) Communication becomes essential at this stage, since each section must connect smoothly with the ones beside it. If one team paints too dark a shade, the whole picture can look unbalanced.

Retailers have discovered practical ways to counteract the negative effects of choice overload without simply reducing the number of products they offer. (A) One common strategy involves organizing an extensive product catalog into clearly labeled categories and subcategories, allowing customers to narrow their search gradually rather than confronting the entire array at once. (B) Another approach highlights a small number of curated recommendations, such as "staff picks" or "best sellers," giving hesitant customers a reasonable starting point without eliminating other options entirely. (C) Both strategies share a common principle: they do not reduce the objective number of choices available but instead reduce the cognitive burden of navigating them.

I thought for a moment before answering that designing posters for school events always felt exciting. Yesterday, I visited my school's career counselor because I felt confused about my future. ( ① ) I told her that I enjoyed both science and art, but I could not decide which subject to pursue. ( ② ) She listened carefully and then asked me a simple question: what activities make me lose track of time? ( ③ ) She smiled and said that this kind of clue often reveals a genuine interest, more than any test score can. ( ④ ) She suggested that I try combining my two interests by exploring careers such as scientific illustration or product design. ( ⑤ ) Our short conversation gave me a clearer sense of direction than weeks of worrying alone had.
